Mapping Skid Trails and Evaluating Soil Disturbance From UAV‐Based LiDAR Surveys in Mediterranean Forests

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil disturbance resulting from forest harvesting activities can have significant and lasting environmental consequences, particularly in sensitive ecosystems such as Mediterranean forests. Skid trails, the routes used by machinery to extract timber, are among the most critical areas of impact, and their detection is critical for assessing ...

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...

A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs$$ {R}_{\mathrm{rs}} $$).Optically significant constituent includes chlorophyll a concentration (Chl a$$ Chl\ a $$), a proxy of phytoplankton biomass ...

Extended Learning Robustness for High‐Fidelity Human Face Imaging from Spatiotemporally Decorrelated Speckles

open access: yesLaser &Photonics Reviews, EarlyView.
A GAN‐based framework is proposed that tackles spatiotemporal instabilities of scattering media and addresses decorrelation between training and testing data (no overlap between their collection periods). The trained GAN non‐holographically retrieves high‐fidelity human face images from unstable scattering media and effectively addresses speckle ...

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens

open access: yesLaser &Photonics Reviews, EarlyView.
The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.
